I can see great potenial, this is a brilliant idea, but there is one thing that kinda dulls the mod, Durability, weapons in Delver can break, just like in FE (excluding Fates). But the Falchion, Parallel Falchion, and Ragnell should not break. (and i mean if your going to add the Binding Blade, it shouldn't break. But if you decide to add Durandal, have it be able to break cause in Blazing Blade, and Binding blade it had durability similar to that of a silver weapon.) But this was just my 2 cents, if you already set up a script that doesn't have them break, great, if not, no worries.

Once I figure out how to make magic wands, I'm going to add some tomes. But yeah, those weapons were next on the to-make list lol

please make more!! i love fire emblem! if i could suggest some, maybe Roy's binding blade, Lyns Sol Katti, Nosferatu could be interesting if you could pull it off, Killing weapons, and more that i cant think of right now, i think this has huge potential!!!!
